SPECIFICATION forming'part of Letters Patent No. '301,831, dated July s, 1884. Application filed April 21', 1884. (No mod el.) l

' To all wiz/om it may concern:

Be it known that I, HUGH BEA, a citizen of the Pennsylvania, have invented certain new and useful Improvements in Oultivators, of which the following is a specification, referencebein g had therein to the accompanying drawings.

This invention pertains to improvements upon my cultivator for which Letters Patent were granted January 8, 1884, No. 291,7 7 2, having for its object vto effect the vertical adjustment or lowering and raising of the rear ends of the plow-beams, to control the depth of penetration of the soil by the plows, and also to facilitate the lateral adjustment of the wings, while rendering the handles capable of adaptation to the height of the attendant, and to accommodate the lateral adjustment of the wings.

The invention consists of means or contrivances to effect the aforesaid results, substanv tially as hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, Figure lis a plan view of a cultivator embodying my improvements, and the other figures, 2 to 7, represent details of the same.

In the organization of myinvention, l connectthe central beam, A, with the hinged or pivoted wing-beams B, which are of the construction shown in my above-referred-to patent, by means of the arms D, pivoted at their outer rear ends in clips a, east with the rear ends ofthe beams B, and pivoted at their inner forward ends in clips b b', connected, as presently described, to the central beam, A; The upper or face part of the clips is aT-shaped casting or plate, b", which is connected to its lower transverseplate, b', by the bolts which connect the arms D to the clips. The forward end of the plate or casting b has alateral eX- tension, b2, through which is inserted -a hooked bolt, b3, having a handled nut upon its upper end, and embracing at its lower hooked end the beam A upon its under side, as seen in Fig. 7.

C C are the handles, which are pivoted, by

' means of the nutted bolt b4, to the beam A at connection having adjusting-slots cl', vwhich receive adj listing-bolts d2 from and thus allow the vertical ad justment of thehandles. At the rear upper ends the handles Glare connected to the win g-bearns B, so as to permit of their vertical and lateral adjustment, according as it may be desired to adapt them to the height ofthe operator or one guiding the implement, or to the lateral movement or adjustment of said wingbeams, said connection being effected by means of the two-part extensible connections D2 D2. Each of the latter comprises two castings or sections-a lower and an upper-the former casting being pivoted or hinged to the top of one of the clips a at'one end, and provided at its otherl end with a vertical slot, e, while the other section or casting is pivoted or hinged at its upper end to a short armor pendant, D',

. bolted to one of the handles and provided with a laterally-bent loop or eye, e", and just above said eye with an adjusting headed bolt, e, and handled nut 63,-said lower section or casting having its slotted portion passing throughthe loop or eye of the upper section, while the adj usting-bolt ofthe upper section passes through the slot of the lower section or casting.

' E E are the supporting caster-wheels of the rear ends of the wing-beams B, which are capable of a lateralA plane of travel and of longitudinal adjustment, the former being to enable them to revolve or move in the direction ofthe flateral adjustment of said wing-beams, while the latter is to permit the vertical adjustment or raising and lowering of the said ends of said beams, to permit of controlling the depth of penetration of the soil by the plows, said adj ustment of the wheels being designated in dotted lines in Fig. 2, and said plane of travel of said wheels being indicated in like manner in Fig. 3. To effect the aforesaid adjustment lof the wheels as to the plane of travel, the spindle f of each axle-frame thereof is supported in. the rearward extension of a rightangled bracket or lever, F, about centrally pivoted upon an upturned extension, G, of

. each beam B, the upper end of said lever having a horizontal slot, f, standing edgewise to the length of the lever and receiving a headed bolt, f2, having ahandled nut, f,which effects the holding of the lever F at the desired point of adjustment. A To secure the aforesaid plane of travel of said wheels, `the spindlef is provided above its bearing in the bracket or lever with an angular shoulder or surface, g, which is embraced by the lower inwardly-extended end of a bail-shaped lever, II, secured in place by a nut screwed upon the screw-threaded end of said spindle, While the upper inwardlyextended end of said lever II is provided with a horizontal slot, h, (sce Fig. 1,) arranged transversely to thc length of said lever. rIhis slot receives an upward screw-thread extension, i, of the lever F, which is also provided With an angular shoulder or surface, j, where it enters said slot, While its extreme upper end is provided with a handled nut, 7c. The angularity of the extension t' and of the spindle f, together with the corresponding shape of the aperture in the lower end of the lever II, and of the slot in the upper end of the latter, enables the disposition and retention o t' the wheel in the required plane of travel by grasping and properly manipulating the lever H and its tightening or holding nut k.

The remaining devices, which consist, principally, of the cultivating plows and shovels, are substantially described in my above-alluded-to patent, and therefore need no further reference herein.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. rIhe combination of the wingbea1ns B, arms D, central beam, A, plate or casting b b, having extension Ul, and hooked bolt b3, embracing the central beam, A, substantially as shown, and for the purpose described` 2. The combination of the handles C, pivoted to central beam, A, Y-shaped connection (Z, having adjusting-slots for coincident adj Listing-bolts, extensible connections D2, wingbeams B, and arms I), substantially as shown and described.

3. The combination of the wing-beams having upturned extensions G, axle-frames of wheels E, having spindles f, bracket or lever F, having horizontal slot f', and lever H, having slot 7L, substantially as shown and de scribed.

Li. In a eult-ivator, the pivoted handles C, adjustable vertically in connection with the slotted Y-shaped connection d, and supportedI by means of the extensible connections l)2 upon Wings I, and the slotted Y-shaped connection d, substantially as shown, and for the purpose described.

In testimony whereof I aix my signature in presence of two witnesses.

HUGH REA.
